Why Did the Sages Institute “VeHu Rachum” Specifically at the Evening Prayer?

Night descends upon the world. A mantle of darkness covers creation, and the lengthening shadows cast a deep silence over the earth. At this hour, when the light disappears and the day reaches its end, a person stands alone before his Creator. His soul trembles as he looks back upon everything he did during the day. The setting sun leaves behind not only physical darkness but also a feeling of awe and concern: perhaps the sins and failures of the day stand accusing him during the dark hours of night. And precisely at this unsettling moment, just before standing in prayer before the King of kings, our Sages instituted a verse of comfort and forgiveness: “VeHu Rachum—He is merciful; He will atone for iniquity.” Why specifically at the entrance to Ma’ariv did the Sages establish this request for mercy, whereas no parallel opening was fixed for Shacharit or Minchah? What spiritual and halakhic secret lies in the night hours that calls precisely then for awakening supernal mercy and requesting atonement?

We turn to Parashat Vayetze, where the roots of the evening prayer are planted: “Jacob left Beersheba and went toward Haran. He encountered the place and lodged there, because the sun had set; he took from the stones of the place, placed them at his head, and lay down in that place” (Genesis 28:10–11).

From this verse our Sages derive that Jacob instituted Ma’ariv as the sun set and night spread over the earth. Jacob stands in darkness and creates a special form of service for the night. This sharpens our question: why was “VeHu Rachum” attached particularly to the prayer Jacob established at sunset? The descent of darkness is a time when a person needs special heavenly mercy and forgiveness for what occurred throughout the day, so that he can enter the night in a state of purification.

Rashi (Genesis 28:11) explains “he encountered the place” as a language of prayer: “Our Sages interpreted ‘encounter’ as prayer, as in ‘do not entreat me,’ and from here they learned that Jacob instituted the evening prayer. Scripture changed its wording and did not simply say ‘he prayed,’ teaching also that the earth contracted for him.” Thus the night prayer emerged from a sudden encounter at sunset, becoming a form of response to darkness through prayer, mercy, and atonement.

Targum Onkelos renders the verse literally: Jacob reached the place, stayed there because the sun had set, took stones, placed them beneath his head, and lay down. This emphasizes the boundary between day and night, when light withdraws and the night calls for protection and mercy.

Targum Yonatan ben Uziel expands upon the miraculous prayer that occurred there and speaks of Jacob praying at the site of the Temple as the sun set unexpectedly. Here too the evening prayer stands opposite the disappearance of light, an hour when man must open the gates of mercy and seek cleansing.

Ibn Ezra understands “he encountered the place” as Jacob turning aside toward that place and arriving there when there may have been no inhabited settlement. Precisely in an isolated place, as the world descends into darkness, a person needs prayer as protection from fear and uncertainty.

Ramban interprets “encounter” as prayer and entreaty. According to his explanation, the evening prayer was called “optional” by the Sages in part because Jacob did not institute it in exactly the same regular manner as the daytime prayers, but encountered it through the circumstances of the setting sun. Since it arises out of the events of the day and the night, it became a natural place for a plea such as “VeHu Rachum.”

Radak likewise notes that “encounter” can mean petition or prayer, as in “do not entreat me.” The very act of standing for Ma’ariv is therefore an act of pleading before Heaven for mercy over the deeds of the day.

Sforno explains that Jacob prayed there because he recognized the place as suited for solitude and attachment to God, especially at the end of the day. The transition into night invites introspection and a pure request for forgiveness.

Hizkuni explains that Jacob arrived suddenly because the sun set unexpectedly early. This sudden descent into darkness led him to establish the evening prayer, again highlighting the need for mercy at the threshold of night.

Rabbeinu Ephraim ben Shimshon links Ma’ariv with the limbs and fats of the afternoon Tamid offering that continued burning through the night. This connects the evening prayer directly to sacrifice and atonement that continue during the nighttime hours.

The Talmudic sources deepen these foundations.

Berakhot 26b states that Jacob instituted the evening prayer, deriving it from “he encountered the place and lodged there because the sun had set,” and from the rule that “encounter” means prayer. Jacob thus poured the institution of prayer into the very reality of nightfall.

Berakhot 4b teaches in the name of Rabbi Yohanan that one who connects redemption to the evening Amidah is a “member of the World to Come.” Although the Exodus was not completed until morning, its beginning was at night, and therefore night itself contains the first stirrings of redemption. The nighttime is thus not only concealment; it is also an hour of beginnings, making it especially appropriate to ask for mercy and deliverance.

Yoma 20b discusses the daily offerings and their times. The afternoon Tamid atoned for the failures of the day, while at night no new Tamid was brought; only its limbs and fats continued to burn. This distinction becomes central to the institution of “VeHu Rachum”: at night there is no new daily offering to provide fresh atonement.

The Jerusalem Talmud, Berakhot 4:1, says that Ma’ariv has no fixed time in the same sense as the daytime prayers because it is not parallel to a new offering, but rather to the limbs and fats that continued burning throughout the night. Since Ma’ariv is not anchored in a newly offered Tamid, the Sages established a special verbal plea for mercy and forgiveness.

The Jerusalem Talmud, Yoma 8:7, states that Yom Kippur atones together with repentance, and that repentance atones for sins not carrying karet or judicial death. This reinforces the idea that whenever a day is completed and one turns toward night, there is a place for awakening repentance and requesting atonement.

The Rishonim provide several distinct reasons for saying “VeHu Rachum” specifically at Ma’ariv.

Sefer HaPardes attributed to Rashi and Shibbolei HaLeket (laws of prayer, no. 49) cite Rabbeinu Eliezer HaGadol based on Midrash Tanhuma: no person ever lodged in Jerusalem while still holding sin, because the morning Tamid atoned for the sins of the night and the afternoon Tamid for the sins of the day. Therefore, at evening and morning we beseech God for forgiveness. In the morning the request is incorporated into other liturgical passages, whereas “VeHu Rachum” was particularly established at Ma’ariv because no new offering is brought at night to atone. On Shabbat and festival nights it is omitted because the weekday Tamid’s limbs are not brought then in the same way, and because the atmosphere is not one of weekday supplication.

Tur (Orah Hayyim 237) cites an additional reason: there was an old practice of receiving lashes in the evening after the sins of the day. Since the lashes served as a form of atonement, people would then recite “VeHu Rachum,” asking for mercy immediately afterward.

Shibbolei HaLeket and Sefer HaPardes also bring a simple and direct explanation: a person sins throughout the day, and therefore in the evening he needs to say “VeHu Rachum.”

Kol Bo (no. 28) and Beit Yosef (Orah Hayyim 237) cite the Tanhuma and explain that because no fresh Tamid is offered at night to atone for the sins of the day, the Sages fulfilled “our lips shall substitute for bulls” by instituting the verse “VeHu Rachum” before Ma’ariv, so that the person enters the night in a purified state.

Among the Aharonim, additional dimensions emerge.

Pri Megadim (Orah Hayyim, Mishbetzot Zahav 237) explains according to Kabbalistic concepts that night is a time when judgment and accusation are stronger in the world. Before the next morning Tamid arrives to atone, we therefore preemptively ask God in His great mercy to forgive sin and remove the accusing forces of the night.

Shulhan Arukh (Orah Hayyim 237:1) records the practice of beginning with “VeHu Rachum” and notes that it is not recited on Shabbat and festival nights.

Mishnah Berurah (237:1) explains why “VeHu Rachum” is omitted on Shabbat and Yom Tov nights: these are not times of weekday-style atonement and supplication; Tahanun is not recited on them; and the weekday afternoon Tamid’s limbs are not treated in exactly the same way on these nights.

Hayyei Adam (28:1) emphasizes the evening as an hour for self-examination. At the end of the day a person should review his conduct, and “VeHu Rachum” awakens the heart to repentance before going to sleep.

Later authorities continue this line.

Maran Rabbi Ovadia Yosef, in Responsa Yehaveh Da’at (vol. 5, no. 54), discusses the custom and its foundations. He explains that the verse was established at Ma’ariv in connection with the absence of a new Tamid offering at night, making it a refined request for mercy before the Amidah.

My teacher Rabbi Asher Weiss, in Minhat Asher, talks on prayer, explains that placing “VeHu Rachum” at the beginning of Ma’ariv is meant to awaken the attribute of Divine mercy in the heart of the worshipper. Even when there is no compulsory offering being brought in the Temple during the dark hours, the gates of mercy and forgiveness are never closed.

Rabbi Yitzhak Yosef, in Yalkut Yosef (Orah Hayyim 237), discusses the order of prayer and the customs of different communities. He explains that “VeHu Rachum” is a meaningful opening to Ma’ariv, through which the person seeks forgiveness for the day’s failures with confidence in God’s kindness and abundant mercy.

Several practical conclusions follow.

First, the distinction between weekdays and Shabbat or festival nights. Since the institution is bound to weekday atonement and to the absence of a new Tamid at night, “VeHu Rachum” is not recited at Ma’ariv on Friday night or festival nights.

Second, an individual praying without a minyan still recites “VeHu Rachum.” It is not Kaddish or Kedushah, but a verse of personal and communal supplication that does not require a quorum.

Third, the verse deserves concentration. Since it was established as a substitute form of pleading where no new nighttime sacrifice atones, the worshipper should say it deliberately rather than mechanically.

Beyond the legal reasons, a profound idea emerges. Night represents the withdrawal of visible light. The day’s actions are already completed and recorded; a person is left to face what he has produced. During daylight, when Israel performs mitzvot and when the daily offerings were brought, holiness appears openly. In the evening, as darkness spreads, a feeling of deficiency surfaces. Precisely then the Sages taught us to invoke Divine mercy, demonstrating that mercy does not depend on visible light. It covers a person even inside concealment.

We can also understand the verse as corresponding to the absence of a new Tamid. The Temple sacrifice is a physical act, a tangible service of blood and offering that atones. At night, when no new daily offering is placed on the altar, only the prayer of the heart remains. The Sages teach that where the physical act is absent, pure thought and a sincere request for mercy can create a spiritual altar. Words of prayer can become the vehicle of cleansing.

The transition from day to night also mirrors the inner states of the human soul. During the day a person is swept into work, activity, and the race of life and can forget his inner bond to the source of life. Darkness forces a pause. When the physical eyes see less, the inner eyes can awaken. Looking back at the failures, exhaustion, and mistakes accumulated during the day can produce sadness or despair. Precisely there “VeHu Rachum” plants the knowledge that even when the visible light fades, the higher light of mercy never goes out.

Day-service and night-service therefore represent two different forms of serving God. Daytime, paralleling the daily offerings, is service through visible action and manifest strength. Nighttime is service of simple faith within concealment. When there is no tangible sacrifice on the altar, the person must offer heart and soul through prayer and supplication. “VeHu Rachum” gives a person strength to believe that even without great deeds to present, a pure turning toward Divine mercy can open the gates of Heaven and renew the soul.

A moral compass emerges from this practice. The first lesson is humility and the courage to face deficiency honestly. An upright person does not flee responsibility. At night, when he reviews the day, he does not justify the erosion of habit or the errors that occurred. Opening Ma’ariv with a request for mercy teaches that perfection is not the absence of failure but the courage to admit it and seek forgiveness with a broken and sincere heart.

A second lesson is to extend mercy toward others. Just as a person asks God to be merciful and not destroy him because of his failings, he should learn to overlook offenses, forgive, and release resentment toward those who hurt him during the day. Entering the night with forgiveness cleanses the soul from anger and enables genuine rest and renewal.

From here we can take several daily practices: break out of routine and say the words of forgiveness and mercy with fresh attention; transform darkness and exhaustion into opportunities for closeness rather than despair; and bring the quality of mercy into human relationships by forgiving, releasing resentment, and entering the night with a clean heart.

The Main Point:

Why did the Sages institute “VeHu Rachum” specifically at Ma’ariv? In Shacharit and Minchah the daily offerings provided atonement for the sins of the relevant period, while at night no new Tamid offering was brought. Therefore the Sages established “VeHu Rachum” as a verbal plea that God forgive the sins of the day. Night is also a time associated with stronger judgment and accusation, and some sources connect the verse with the old practice of receiving lashes before Ma’ariv and then immediately seeking mercy.

At the end of a crowded day, when no physical sacrifice remains to be placed on the altar, the gates of Heaven are opened through pure words. Divine mercy does not wait for a day overflowing with achievements. It breaks through precisely from darkness and a broken heart. When a person dares to examine his soul, forgive others, and place his trust in his Creator, darkness itself can become a spring of atonement and renewal.
